Carburetor Main Jet #115, GY6 125/150. 152QMI 152QMJ 157QMI 157QMJ B-200-1005-3005
$5.14 $3.95 Add to Cart

This is a carburetor main jet (M5 x .8, length 8mm) for the GY6 125cc and 150cc 152qmi and 157qmj engines. These are pretty easy to replace and a must if you want to upgrade your engine's performance with performance parts or upgrades.

Mechanics Note: If you increase the size of your stock carb jet you will want to improve your air flow both in and out of the engine.  For smaller upgrades replace the stock air filter with a Performance Air Filter for this engine.  If you upgrade beyond small adjustments you will want to install a Performance Exhaust to handle the increased combustion and minimize back flow issues.

Altitude can play an issue in scooter performance. When you are dealing with elevation you will want to rejet to prevent your engine from siezing and requiring a rebuild.  You will loose about 3% in power for every 1000' in elevation. At 4000' feet you will have lost about 12% of your power output.  You will want to go down one (1) jet size for every 1750' to 2000' you go up in elevation.  When the air is colder it requires bigger jets because cold air is more dense. If it is 50 degrees colder you would increase your jet size at least one step up.  If you don't your engine can sieze on you.

These are performance torque springs for the Chinese made GY6, 4T, 125/150cc engine 152QMI, 152QMJ, 157QMI, 157QMJ installed on scooters, quads, mopeds, ATVs, buggies and go-karts. These come in 1K, 1.5K, and 2K spring rates.  These are Performance Torque Springs to maximize your engine's torque and response. These top performing springs will give you back your acceleration, hill climbing ability and make your machine run as a top performer once again. Torque springs should be changed about every 800 miles because of heat and fatigue.

Mechanic Note: Torque Springs come in (3) different rates or RPM ratings, 1000 (1K) often Blue, 1500 (1.5K) often Yellow, and 2000 (2K) often RED. The lowest rated 1K may give you a higher speed overall but will engage at a lower RPM on take-off. If you or your scoot are heavy, you may be disappointed in the initial torque, take off and acceleration. The 1K will also have the hardest time "pulling the hills". On the other end the 2K will give you the greatest grabbing power and a higher RPM at take-off, and will pull the hills the best, but may be slower in speed overall. The 1.5K is in the middle. If you go with a heavier torque spring, you may want to go to a slightly higher variator roller or slider weight. At the same time, if you go to a lower RPM spring, you may need to go to a lighter weight. It is a fine line to find balance between torque spring and variator roller weight, achieved only through trial and error
